Billy Bob's toilet idea denied

Billy Bob Thornton offered to wet himself for real on camera while making his new movie 'Bad Santa' - just to make it more authentic.

Billy Bob plays a sex-crazed, foul-mouthed Santa in the controversial movie and his character has to wet himself a couple of times.

After getting the go-ahead from the director for his master plan, he failed to get it passed by the special effects people who said that actual urine wouldn't show up on his clothes as well as the fake glycerine substance that they proposed to use.
